Irrationality Game:

Non-healthcare related personal quality of life advances since around 1955-1965 (improvements in food, clothing, entertainment, transportation, communication, etc.) do not increase personal happiness due to the hedonic treadmill, and most of the advances have come about as a means to capture consumers' median increase in real wealth due to a more efficient economy caused by technological advances. Furthermore, if a consumer hypothetically had access to the 1960 basket of consumer goods produced using 2014 technology, a consumer could live at or above the current middle-class level of happiness by spending about $15,000 annually for an average household of three. ~85%.

Please note I am referring only to personal consumer goods and NOT business or technological improvements such as manufacturing techniques, computing power, automation, etc.
